I dig, shovel, carry rock and SWMBO clears out the “too many” grass and “Snow in Summer” roots. And every once in a while we have to move a BFR, but it’s getting there.
Squeezing the station into that space will require some selective compression.
In addition to the footprint of the original (GIS map), I also use some of the screen shots grabbed from Google Street View. The Albula-Bernina line has been capture by Google; I don’t know how much that had to do with the lines gaining “UNESCO World Heritage Sites” status.
In any case, looking for specific details along the Albula line has become a lot simpler, add the Panoramio pictures in Google Earth to that and it is “Happy Camper” time.

Most of the station buildings along the different RhB lines use common “Type” designations, as do most other railway buildings along the lines. Having the authoritative book on these items in my library does the rest. i.e. if I want it 1:22.5 I just build it to that scale.
